Question

Study the data give below in the table and answer the question that follow:

Crops	Area (in lakh hectares)		Production (in lakh hectares)		Yield (in kg/hectares)
	1950-51	2015-16	1950-51	2015-16	1950-51	2015-16
Wheat	97	302	65	935	663	3093
Rice	308	434	206	1,043	868	2404

1. What is the proportional increase in the production of each of the two crops during the given period?
2. Of the two crops whose yield per hectare has shown more impressive increase?

Answer 1

i. Proportional Increase in Production (1950–51 to 2015–16):

Proportional Increase = `"Production in 2015–16 − Production in 1950–51​"/"Production in 1950–51" xx 100`

Wheat: `(935-65)/65 xx 100 = 870/65 xx 100 = 1338.46%`

Rice: `(1043-206)/206 xx 100 = 837/206 xx 100 = 406.31%`

ii. Crop with More Impressive Increase in Yield per Hectare:

• Wheat Yield Increase:
  From 663 kg/ha to 3093 kg/ha
  Increase = 3093 − 663 = 2430 kg/ha
  Proportional increase = `2430/663 xx 100 ≈ 366.5%`
• Rice Yield Increase:
  From 868 kg/ha to 2404 kg/ha
  Increase = 2404 − 868 = 1536 kg/ha
  Proportional increase = `1536/868 xx 100 ≈ 176.9%`

Wheat has shown a more impressive increase in yield per hectare.
